NVIDIA's jaw-dropping Tegra 4 and Project Shield demos showed off a lot of impressive hardware, but any gamer will tell you: it's all about the games themselves. To that end, they've revealed a few of the games currently in development and set to take advantage of both the Tegra 4 and Shield's console-style controls. We've already seen Madfinger's Dead Trigger 2, but on the shiny new Shield website, there are brief glimpses of other titles.
Blood Sword: Sword of Ruin
First up is Blood Sword: Sword of Ruin. This is the first time we've seen the game, but based on the screenshot, it seems to be a Devil May Cry-type fantasy hack-and-slash action title. This one should make good use of the controller.
Real Boxing has already been released for iOS, to generally positive reviews. Graphics look extremely impressive, even better than the iPad counterpart. Based on the polish in the demo in the CES press conference, it may be released before the Shield comes to fruition.
Burn Zombie Burn
Burn Zombie Burn is available right now on PC and consoles, and it is almost a carbon copy of the excellent top-down shooter Age of Zombies... right down to the Bruce Campbell-inspired hero. This one would probably work just fine on current Android hardware.
Rochard
Rochard is another downloadable game already released on Steam and consoles. Gameplay uses a cartoony version of the Gravity Gun from Half Life in 2D platforming and puzzles, but the crisp visuals are in full 3D. This is another one that would benefit from precision control that's nearly impossible with touchscreens.
ARMA Tactics
Perhaps the most exciting game tied to the Tegra 4 is ARMA Tactics. The ARMA series of PC games blends typical first-person shooter gameplay and real-time strategy, allowing you to command entire squads or order individual units in real-time play. The Android version has never been discussed before, though NVIDIA's brief teaser mentions that the mobile game will be turn-based instead of run-and-gun. Below is the only look at ARMA Tactics available.
The site also mentions Sonic The Hedgehog 4: Episode II, a game which has already been released, but does come in a version tailored for the Tegra 3. That would imply that NVIDIA will incentivize developers to make older titles compatible with Shield's physical controls, even if the graphics aren't spruced up for the Tegra 4 architecture. It's also reasonable to assume that all of these games will be released on Google Play either before or after Shield's hardware release, though whether they'll be "THD" Tegra exclusives is still up in the air.
